Knoll Keyboard Trays are a sturdy and versatile way to get your keyboard and mouse in your lap, putting you in a relaxed ergonomic position as you type and mouse by allowing you to adjust the height of the platform with their easy lift-and-lock, knob-free adjustment. Knoll platforms come standard with 360 degrees of pivot at the mechanism, with the option of a second pivot point at the platform to allow it to rotate independently from the rotation of the mechanism, keeping the platform parallel to your desk as you rotate the arm.

For users who need a separate swiveling mouse platform, there's the light and compact Act II Keyboard Platform or the strong and durable Romeo + Juliet Keyboard Platform. For one surface for both your keyboard and mouse, there's the solid and sturdy Prospero Keyboard Platform, or, for the more environmentally conscious, the Knoll Act I Keyboard Platform, available in a 100 percent recycled/recyclable medium-density fiberboard. With three different arm options for varying height adjustment needs available on every model, it's easy to find the Knoll Keyboard Tray that's right for you.

Knoll Keyboard Trays, like the Knoll Prospero Keyboard Platform with its dual cable management loops on either side, or the Knoll Act II Keyboard Platform with its swiveling mouse platform that can be mounted on the left or right side or upgraded to dual mouse platforms, have several features that encourage ambidextrous mousing. We recommend switching between mousing hands periodically to combat or prevent repetitive stress injuries.

Completely satisfied with the desk. More impressive was the buying process, knowledge of the sales and support staff, and attention to detail. It's clear that this company is on a mission to help people. They have found a way to differentiate themselves in a crowded market and stand out as a great company which deserves all the success it achieves. We will be adding a second UpLift 900 in the near future. Thank you!
